    +Hisilicon Hi6421v530 Power Management Integrated Circuit (PMIC)
    +
    +The hardware layout for access PMIC Hi6421v530 from AP SoC Hi3660.
    +Between PMIC Hi6421v530 and Hi3660, the physical signal channel is SSI.
    +We can use memory-mapped I/O to communicate.
    +
    ++----------------+ +-------------+
    +| | | |
    +| Hi3660 | SSI bus | Hi6421v530 |
    +| |-------------| |
    +| |(REGMAP_MMIO)| |
    ++----------------+ +-------------+
    +
    +Required properties:
    +- compatible: Should be "hisilicon,hi6421v530-pmic".
    +- reg: Base address of PMIC on Hi3660 SoC.
    +- interrupt-controller: Hi6421v530 has internal IRQs (has own IRQ domain).
    +
    +Example:
    + pmic: pmic@fff34000 {
    + compatible = "hisilicon,hi6421v530-pmic";
    + reg = <0x0 0xfff34000 0x0 0x1000>;
    + interrupt-controller;
    + #interrupt-cells = <2>;
    + }
